Prospex Marinemaster 1968 Heritage Diver’s Watch JAMSTEC Limited Edition. Seiko Prospex challenges every limit with timepieces created to exceed expectations, engineered with superior style and innovative technology for the sea, sky or land. Driven by rich legacy that has set the standard for dive watch specifications and a heritage of iconic design, Prospex continues to keep going forward with precision timekeeping, crafted for the modern world. Marking Seiko’s partnership and support for the Japan Agency for Marine-Earth Science and Technology (JAMSTEC), this striking Limited Edition is part of the high-intensity Marinemaster collection, complete with a specially engineered, highly accurate mechanical movement and rugged features designed for intrepid divers. Available only in a controlled production run of 1,000 pieces, with the serial number and “JAMSTEC LIMITED EDITION” showcased on the screwdown caseback, the striking design draws inspiration from the construction of “Mirai II,” Japan’s first icebreaking polar research vessel, featuring a uniquely textured blue dial expressing the ship’s trail through drifting ice. Framed by uni-directional rotating bezel with super-hard coating and deep knurling for the ultimate in durability and ease of use, the captivating dial is coated with a thick layer of transparent paint, meticulously polished for a lustrous finish that evokes the awe-inspiring beauty of the polar regions, and includes LumiBrite coating on the hands, markers, and 12 o’clock bezel marker for superior visibility in low-light conditions. Created with an enhanced 300 meter water resistance, this homage to Seiko’s 1968 Diver’s watch is powered by Seiko’s hand-assembled 35-jewel 8L45 movement that beats at a frequency of 28,800 vibrations per hour with a power reserve of approximately 72 hours, 3 full days and offers enhanced accuracy for the ultimate in precision timekeeping. Crafted of stainless steel with super-hard coating, this rugged high-performance watch also includes an anti-reflective sapphire crystal, a date calendar, secure screwdown caseback, and a tri-fold push button release clasp with secure lock and slide adjuster, allowing for precise size adjustments on the wrist.

First off, I want to say that I absolutely love my new Seiko SPB503J1 “Alpinist”, which I purchased from Hislon Jewelry. At 34, it was finally time to buy my first “big boy” watch, and after extensive research, I landed on this absolute beauty. I contacted multiple authorized Seiko dealers in the area, and Hislon Jewelry was the only one that not only had several Alpinists in stock but was also willing to accommodate my late schedule. From the moment my wife and I walked into their showroom, I knew I made the right choice. Their display featured an impressive collection of Seiko, King Seiko, Michele, Tissot, and Rolex watches—clearly a store that takes pride in quality and selection. We were helped by Paige, who was both kind and extremely knowledgeable. However, what truly set Hislon Jewelry apart was the customer service that followed after the sale. I’ll admit—I can be a bit neurotic when it comes to expensive purchases. After leaving the store wearing my watch, I started to worry that the clasp might not be fully secure (this may very well have been in my head). My wife suggested we stop by the next morning to have it looked at. Once again, Paige assisted us, and whether my concern was valid or not, she handled everything with complete grace and professionalism. She offered to swap the watch for another one and readjusted it so it fit perfectly. She never made me feel rushed, dismissed, or uncomfortable. Instead, she made me feel heard and taken care of—and that speaks volumes about the level of professionalism at Hislon Jewelry. I am 100% satisfied with both my purchase and the service I received. I would highly recommend Hislon Jewelry for all your watch and jewelry needs, and I will absolutely be back when it’s time to add the next piece to my collection.

I can’t say enough good things about this jewelry store! The staff are honest, reliable, and truly care about their customers. They take the time to explain everything and make sure you’re completely comfortable with your purchase. It’s such a relief to find a jeweler I can trust — I won’t go anywhere else now!

I‘ve always shopped at big box jewelry stores and this week I came across this nice gem of a place -no pun intended- Hislon Jewelry. The first thing that caught my attention was the selection of watches, but I was on a mission to buy a chain. Jeff greeted me and showed me the different chain styles and gave me a lot of information on the price of gold. I felt very comfortable and the quality of the fine jewelry was excellent. I definitely enjoyed my shopping experience and I won’t be going to a big box store anymore!
